HSO4-, + HNO2, = acid + base

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
